SpeTool 5Pcs Tapered Ball Nose Carving End Mill 1/8 inch Shank 0.25MM Radius (0.5MM Diameter) Tips 3D Woodworking Tool CNC Router Bits

Why did you pick this product vs others?: I used these all the time for my small business, they cut well and can the 2 flute design works great with ABS, I cute ABS enclosures on my bench-top CNC. These bits are real workhorses, I can get over 25 enclosures, so thousands or MM of cutting 3.74mm thick ABS plastic. My own mistakes are the only reason I have to change bits, otherwise, they just keep going and going.

Worked great after a 13 hour carve. Still going strong. I'm impressed.

I had been trying to do some fine engraving in brass using 0.1mm tip flat grind engravers, and struggling mightily. Even though these tools have a bigger tip, I re-worked my design to accommodate the size difference and what an amazing difference. These are cutting much better, and LASTING. After a few test cuts the tip looks perfect at 40x macro. The old point engravers would lose their tip almost immediately. These having two flutes helps to. As long as my design and handle the larger size, I'm glad I switched. Running at 24k rpm, 0.25mm depth of cut, .5mm width of cut.

Very good set of bit and at a great price. They worked very well in my CNC router and produced the results that I was wanting.

These bits, along with a better quality hardwood, have caused my CNC carves to come out sharper.

I was surprised how much I like these REALLY wanted 1/4" shank but could not find any with next day delivery so I got these 1/8". I actually like them better. I am doing small very intricate, true 3d carving, ornate chess pieces, and the small shank size is a benefit. Really happy with these end mills.

I do alot of 3d cnc milling on walnut. This bits are sharp and last along time. They leave a amooth finish and get into thoughts hard to get spots. Ive tried some other brands and these are the best I have found so far

I bought a 5-pack of these bits for $20, not expecting much. The first bit held up really well through a 10 hour hardwood (cherry) 3D carve. Still sharp afterward. I used the same but as an end mill to cut out some laser cutting design from 1/8" plywood. The bit is still sharp. If the other 4 bits in the pack hold up this well, they're a steal at $20.

Good ball nose geometry, excellent finish

ok

Für den Preis Spitzenware.

Con estas pequeñas herramientas de grabado me apoyo para marcar y grabar bases de acero 1018, 12L14 y de aluminio. Trabajan excelentemente y duran 20 veces más que un cortador vertical de carburo del mismo dímetro. 18,000 rpm, lubricación y avances de 200mm/min X 0.125mm (0.005") de corte por pasada y durarán muchísimo

The grind seems to be good, but the tip diameter is actually 2.2mm. It is OK for my use and could be just my batch, but do make sure you measure them before using.
